`open_payments_company_history`

Pack: cms-open-payments · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/open_payments_company_history for the schema, then POST the same URL with its arguments for the data.

Build a cross-year CMS Open Payments history for a company-name substring. Annual counts are authoritative for that query; dollar figures cover only the returned bounded sample and company aliases may split or combine legal entities.

Parameters

Name	Type	Required
`company`	string	yes
`from_year`	number	no
`to_year`	number	no
`payment_type`	string	no
`sample_per_year`	number	no
